2. Object pad
The object pad provides tools for manipulating, measuring, and annotating datasets. It appears when a dataset is loaded from the library.

2.1
Cutter
Enables precise cuts through the datasets. Select it with the right trigger to activate the cutter on your left controller; press again to switch it to the right. Move your hand into the model to see a live cut. Pull the left trigger to fix the cut. To remove it, point your laser at the red X. Use the marker’s cut visibility button to show/hide cuts.
2.2
Laser
Turns on the laser, by default on your right controller. Use the laser to point at interface elements, and press the trigger to select or activate them.
2.3
Masking
Lets you focus on specific regions of a DICOM dataset by modifying their visibility. Use your controller like a brush to 'paint' areas in the 3D image - depending on the selected mode, the marked region will be hidden, isolated, or highlighted. Pressing the mask button with the trigger opens an additional panel and displays a red ball at your controller’s fingertip. Masking requires a lot of rendering power so it is recommended for PC-VR setup.
2.3.1
Mask size
Adjusts the red ball’s size. Use the slider to set the desired width.
2.3.2
Mask mode
Allows switching between different masking modes.
- Isolate: keeps only the selected area visible
- Hide: hides parts of the dataset
- Highlight: visually emphasizes selected areas.
2.3.3
Mask mode
Restores masked areas. Point at the region, hold the trigger to unmask, then release.
2.3.4
Mask channel
Let you organize and separate different masked areas within your DICOM dataset. Switch channels to apply and manage varied masking effects.
2.3.5
Mask volume
Shows the volume of the masked area on the selected channel.

2.4
Measure area
Allows area measurement. Press it with the trigger and a black cone will appear at your controller’s fingertip. Press the trigger to place points and outline your shape. To close the shape, move the cone near the first point and press the trigger when the click to close the shape prompt appears. The surface area will then be displayed in square millimeters (mm²).
2.5
Measure distance
Allows distance measurement. Press it with the trigger and a black cone will appear at your controller’s fingertip. Press the trigger to set the start point, move to the endpoint, and press again to display the distance in millimeters.
2.6
Delete
Removes objects like measurements, shapes, or drawings from the workspace. A red X will appear on your controller - aim at the object and press the trigger to delete it.
2.7
Scale
Resizes the active dataset. Press it with the trigger to enter scaling mode. Move the controller up or down while holding the trigger to adjust the size, then release the trigger to set it.
2.8
Move
Repositions the active dataset. Aim at the button, hold the trigger to move the dataset, and release to place it.
2.9
Move backward
Adjusts the dataset’s distance. Aim at the button, hold the trigger and move the controller up or down to bring it closer or farther while holding the trigger. Release to set the position.
2.10
Frame rate
Displays performance in FPS, helping you monitor app smoothness.
2.11
Remove dataset
Deletes the active dataset. Press it with the trigger to remove it from the scene.
2.12
Light on/off
Controls dataset lighting. Press the trigger to toggle the light on or off. In Medical Imaging XR, lighting is available only in PC-VR mode due to performance limitations.
2.13
Measure angle
Measures angles in VR. Press the trigger to set the angle’s vertex, then define the two line endpoints. The angle in degrees appears instantly once both lines are placed.
2.14
Draw
Enables drawing. Aim your laser at the button, press the trigger, and move your controller to draw lines. An additional panel will appear. Release the trigger to stop drawing.
2.14.1
Stroke width
Use the stroke width slider to adjust the line thickness. Aim your laser, pull the trigger, and adjust the size to your preference.
2.14.2
Color
Select your desired color and press the trigger to update the drawing tool's color.

2.15
Marker
Places visual markers in the scene. Aim your laser at the button, press the trigger, and a colored arrow will appear at your controller’s fingertip. Move it to the desired location and press the trigger to place the marker.
2.16
Rotate horizontally
Rotates the active dataset left or right. Hold the trigger while moving the controller horizontally, then release to set the angle.
2.17
Rotate vertically
Tilts the dataset up or down. Hold the trigger and move the controller vertically, then release to set the angle.
2.18
Handle
Repositions the panel. Select it with trigger and release to set it to a new position.
